I don't know of any publicly available fix. My version of ext2fs avoids the bug by doing buffering differently. As a workaround, unmount ext2fs file systems before rebooting. Unmounting most file systems before rebooting should be the default anyway (handled by shutdown(8) and reboot(8)), since unmounting may fail and vfs_unmountall() in the kernel has no good way to log errors.
